QSG Verkehrstechnik

What QSG Verkehrstechnik does

QSG Verkehrstechnik GmbH is a German traffic-engineering specialist founded in 1989 in Dortmund, designing and implementing traffic control and dynamic signage systems for highways, tunnels, and urban road networks. The company develops both hardware and software in-house, with a core product portfolio spanning Streckenbeeinflussungsanlagen (SBA) for highway line control, Netzbeeinflussungsanlagen (NBA) for network-wide traffic coordination, dWiSta digital variable message signs using full-matrix RGB LED technology, Verkehrsdatenerfassungssysteme (VDE) using certified classification detectors, and complete Tunnelverkehrssteuerungen including tunnel traffic computers (TVR) and Unterzentralen (UZ) sub-control centers. Notable installations include control systems for A94 Tunnel Tutting, A49 Tunnel Frankenhain, A81 Engelbergtunnel, B2n Tunnel Oberau, A40 Rheinbrücke Neuenkamp, and over 200 permanent counting stations deployed across North Rhine-Westphalia since 2010.

The company serves exclusively German public-sector transportation authorities — including Die Autobahn GmbH des Bundes, Straßen.NRW, Hessen Mobil, Regierungspräsidium Karlsruhe, and municipal clients — through direct project awards via public tenders. Its business model combines one-time infrastructure project installation revenue with ongoing service and maintenance contracts, augmented by participation in ARGE working groups (notably with SPIE OSMO for tunnel projects). The firm is currently managed by Lutz Breitbarth and Birka Breitbarth (joined as co-Managing Director on 01.10.2025), employs 45 people across offices in Dortmund, Berlin, and Bad Bramstedt, and holds PQ certification and membership in major industry bodies including ITS Germany, STUVA, Bitkom, ZVEI, and BVMW.
